through the lenses, and every ray must pass through two lenses, with the result that there is a maximum diiusion of light without dark spots. While a maximum of diffusion is more possible with an infinite number of angular lenses, a great number of dark spots would result by such form of lenses, whereas with the present arrangement a maximum diffusion ensues without introducing dark spots. The rows of lenses on both sides of the sheet coincide and the lenses of the respective coinciding rows are arranged in staggered relation, whereby the overlapping of the fiat surfaces on one side by the lenses on the other side is reduced.

The glass has a wide range ofp application, and it can be used in any place where a ground or other translucent glass is desired. The glass will be found particularly useful for motor 'hts to eliminate' or reuce the objectiona e 1n-v tense gmc, and also for otice partitions, windows, etc.

I claim:

1. A glass structure having both of its To all whom t may concern.'

Be it known that I, EMIL G. JoHANsoN, a subject of the King of Sweden, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Light-Rays Refractors, of which the following is a specification.

This invention relates to glass structures having a surface so formed that light rays are transmitted ditlusely, and its object is to provide a novel and improved structure of this kind in which the surface of the glass is provided with an arrangement of protuberant lenses whereby the object sought is most eifectively attained.

In order that the invention may be better understood, reference is had to the accompanying drawing in which- Figure l is a plan view of a fragment of the glass; i

Fig. 2 is a cross section on the line 2 2 of Fig. 1;

Fig. 3 is an enlarged plan view of a fragment of the glass, and

Fig. 4 is a similar view showing the opposite side of the glass. sides formed with protuberant lenses ar- Referring specifically to the drawing 5 ranged in straight parallel rows, the lenses denotes a Hat or otherwise formed sheet of of one row being located at an angle of glass having both of its faces provided with lsixty degrees with respect to the lenses of protuberant circular convex lenses, the the adjacent row on the same side. lenses on one face or side being shown at 6 2. glass structure having both of its and those on the other face at 7. On both sides formed with protuberant lenses arsides of the glass, the lenses are arranged in ranged in straight parallel rows, the lenses straight parallel rows, and the lenses of of one row being located at an angle of sixty one row are located at an angle of sixty degrees with respect to the lenses of the degrees with respect to the lenses of the adadjacent row, and the lenses of the respecjacent row. By arranging the lenses in this tive sides being staggered. manner the closest setting is possible, and 3. A glass structure having both of its a maximum number of lenses in a given sides formed with protuberant lenses ararea may be provided. The lenses are arranged tangentially with respect to each ranged tangentially with respect to each other and in straight parallel rows, the other, with fiat surfaces between the nonlenses o f one row being located at an angle contiguous portions of the lenses. The surof sixty degrees with respect to the lenses of faces are denoted by the reference character the adjacent row. 8 on one side of the sheet and by the refer- 4.

A glass structure having both of its can pass through the glass without passing sides formed with protuberant lenses erranged tangentially in straight parallel rows, the rows of lenses on the respective sides coinciding, and the lenses of said coinciding rows being staggered.

6. A lass structure having both of its sides formed with protuberant lenses arranged tangentially, with iiat surfaces beture.
